ASHRAE has announced the release of the 2018 International Green Construction Code (2018 IgCC), which is a joint initiative of the US Green Building Council (USGBC), International Code Council (ICC), ASHRAE and the Illuminating Engineering Society (IES).

As part of a new report by the Environmental Investigation Agency (EIA) on the implications of illegal CFC production and use, they have called for a global ban on disposable, non-refillable refrigerant cylinders to tackle the problem with illegal refrigerants.

The range over which temperatures decrease, from the lower limits of general commercial and industrial refrigeration down to absolute zero, covers a zone described as ‘cryogenic’ — a rather old word for an area of technology that became commercially active only fairly recently.
